That was part of the danger that I was referring to - that their very existence would make them a target or catalyst in creating a war. But that's not logical, as the Daleks were waging war against the entire universe anyway, and would conquer it quicker without a force powerful enough to at least hold them at bay (the Time Lords).
Just because the "Doctor Who" story universe only focused on the Daleks targeting the Time Lords, it doesn't mean they were the only race they wanted to destroy... it's not like the Daleks would be a quiet peaceful race if the Timelords never came back.
And yet other races blamed the Timelords (according the Moffat), for being caught up in the crossfire of Timewars... but they would have died at the hands of the Daleks anyway if the Timelords didn't exist to fight back. (that was another flaw of the T.o.t.D. as the Church were trying to prevent a war by keeping the Timelords out of this universe, but in reality it meant no one would then be left to stop the Daleks from taking over the universe)
